An explorer from medieval China may have visited an island off the coast of Kenya, archaeologists say.

A joint expedition by The Field Museum and the University of Illinois at Chicago unearthed a 15th-century Chinese coin on the Kenyan island of Manda, according to a Field Museum press release. Starting around 200 A.D., Manda was a trading hub and home to an advanced civilization.

The coin, shown here, is an alloy of copper and silver and was issued by the Ming Emperor Yongle, who reigned from 1403-1425 A.D. The coin bears the emperor’s name.

Emperor Yongle sent Admiral Zheng He, also known as Cheng Ho, on an epic mission of exploration to find new trading partners. He traveled around the coasts of south and southeast Asia, east Africa as far north as Somalia, and the Arabian Peninsula.

“Zheng He was, in many ways, the Christopher Columbus of China,” said Dr. Kusimba, curator of African Anthropology at The Field Museum. “This finding is significant. We know Africa has always been connected to the rest of the world, but this coin opens a discussion about the relationship between China and Indian Ocean nations.”

Sadly, later Chinese rulers took a more insular policy and banned foreign expeditions. If they had continued Yongle’s work, the great Age of Exploration may have been more Chinese than European. Manda was mysteriously abandoned around 1430, shortly after Emperor Yongle’s death.

While the focus has been on Kenya, researchers might want to take a look at the city of Harar in Ethiopia, which has been a trading center for centuries. Some Hararis have vaguely Chinese features, and Harari coins have been found in China. When I was doing research there some Hararis told me that the city used to trade with China many centuries ago.

This week I learned the sad news that a friend and coworker in Harar, Ethiopia, had died. Mohammed Jami Guleid helped me out countless times while I explored the Horn of Africa. If you enjoyed my series on Somaliland or Harar, you have him to thank.

I first met “Dake,” as everyone called him, on my first visit to Harar in eastern Ethiopia as I was searching for a way to get to Somaliland, the breakaway northern region of Somalia. Everyone told me to meet with Dake. He was a Somali who had made Harar his home and had many contacts on both sides of the border. Within days I was riding through the desert with a couple of his relatives on my way to Somaliland. It was one of the best adventures of my life.

From that point our working relationship grew. Dake was an expert on Somali and Harari culture. He even wrote a book titled “Harar: A Cultural Guide.” My signed edition sits next to me as I write.

We meet lots of people on our travels. Most of them soon fade into the past, remembered only in old photographs and journal entries. Others last through a few emails and postcards before they, too, become memories. Only a few become lasting friends.

That was easy with Dake. He had an open, relaxed manner and was always quick with a joke. His deep interest in Harar’s history and architecture was infectious. Once he woke me up at five in the morning so we could photograph the town’s winding medieval alleys as the sun rose. I didn’t mind, even when his insistence on getting “one more shot” kept me from my morning coffee for far longer than I liked.Here he is in the narrowest of Harar’s alleys, called Megera Wa Wiger Uga, “The Street of Peace and Quarrel.” In local tradition you have to speak to anyone you pass here, even if you’re angry with them and aren’t otherwise talking with them. Since it connects two busy areas, a lot of people pass through this alley and a lot of arguments get resolved.

Dake had been an outsider to Harar once himself, so he sympathized with my efforts to adjust to the local culture. He was always ready to help out with advice at a moment’s notice and saved me from more than one cultural blunder. Having an insider who knows what it’s like to be an outsider is invaluable when studying a new place.

We also explored Ethiopia’s Somali region. Dake had big hopes of developing the region’s tourism potential as a way to expand his own tourism business while helping his people.

When we weren’t working at documenting eastern Ethiopia’s heritage, we spent many relaxed hours at birtchas or spinning tales in local cafes. Friendships can be fleeting when you’re traveling, but Dake and I became good friends and kept up a regular correspondence when I was back in Europe.

When you make a real friendship on the road, treasure it. Keep in contact and head on back to see them. I wish I had made it back to Harar at least one more time while he was still alive. As the list of my friends who have died relentlessly lengthens, I find myself more appreciative of those I still have, and more determined to pack as much life into the years left to me before my own inevitable end.

Authors note: my pay for this post will be donated to Glimmer of Hope, an NGO working to help Ethiopia’s children. Dake had a son about the same age as mine so I think he’d appreciate it.

The Dutch government recently announced that it will ban the use of khat, a narcotic leaf widely chewed in the Horn of Africa and Yemen.

I’ve written about khat before. I’ve spent four months in Ethiopia, especially Harar, a city in the eastern part of the country where chewing khat (pronounced “chat” in the local languages) is part of many people’s daily lives. It’s a mild drug that makes most people more relaxed, mildly euphoric, and talkative. It also helps concentration and is popular among university students.

Of course there are side effects. Short-term effects include sleeplessness, constipation, and for some people a listlessness that keeps them from achieving their potential. Long-term use can lead to mental instability and heart trouble. I met one western researcher in Harar who had been there two years. He’d stopped using khat after the first few months because he was afraid of the long-term effects. If I lived in Harar that long I’d stop chewing khat for that very reason.

So the Dutch government seems to have a good reason to ban khat. Or does it? This is a country where marijuana, hash, herbal ecstasy, and psychedelic truffles are all legal. And if we’re talking about long-term health effects, we need to throw in alcohol and tobacco too.

So what’s different about khat? It’s almost exclusively used by the Dutch Somali community, numbering about 25,000 people. According to the BBC, “a Dutch government report cited noise, litter and the perceived public threat posed by men who chew khat as some of the reasons for outlawing the drug.”

Drunks aren’t noisy? Cigarette smokers never litter? The last reason is the most telling: “the perceived public threat posed by men who chew khat.” In other words, black men. In Europe, khat is a black drug, little understood and rarely used by the white population. This ignorance and the fear it generates are the real reasons khat is being banned.

While there are some valid health and social reasons for banning this narcotic plant, they also apply to the narcotic plants white people like to use. But we can’t expect white people in The Netherlands to give up those, can we?

This was a strange year for me. I didn’t see any new countries but I still had some great adventure travel. I spent two months living in Harar, Ethiopia, writing a series about it for all you fine folks. I’d visited this fascinating medieval walled city back in 2010 during a road trip in Ethiopia and passed through on my way to Somaliland. The three weeks I spent in Harar in 2010 convinced me I had to come back and learn more.

This time, however, I came to settle in for a while. My colleague–local historian, author, and guide Mohammed Jami Guleid (harartourguide @gmail.com)–helped me explore Ethiopia’s Somali region and meet the Argobba, a little-visited tribe. Other highlights included feeding a pack of hyenas and meeting a traditional African healer. The best part of my stay, however, was the day-to-day life of visiting friends and making new ones. Harar is a small town and it seemed that by the end of my two months there everyone knew me.

Sadly, that was my only adventure travel in 2011. I didn’t get to do my usual long-distance hike, scheduled in late August right after my birthday. I like to do these to prove to myself that I’m not old yet. In previous years I’ve blogged about hiking the East Highland Way and Hadrian’s Wall. Hopefully I’ll bring you another long-distance hike in 2012.

My main adventure travel destination this coming year is the Orkney Islands. My family will be along for this one and we’ll be exploring these rugged isles far to the north of Scotland. I’ve always wanted to see the Orkneys for their bleak grandeur and archaeological sites such as the mysterious brochs and stone circles like the Ring of Brodgar, pictured below courtesy flickr user joeri-c. Last summer I checked out an Ordnance Survey map of Orkneys and found that the farm right next to it is called “Sean”. Looks like I’m fated to go.

Other plans include a short trip to The Gambia and another trip back to Ethiopia. I need to get some funds for both of these adventures so I can’t guarantee they’ll happen. If they do, you’ll certainly hear about it!

Of course I wasn’t the only Gadling blogger to have adventures. The one that made me most jealous was Alex Robertson Textor’s series on Far Europe, and of course Jon Bowermaster is always doing something cool.

The recent fighting in Libya that toppled Gaddafi destroyed many lives and laid waste to many neighborhoods. Now that the country is beginning to rebuild, Libyans are taking stock of other effects of the war.

Libya’s beautiful Roman remains, it appears, got off easy. Earlier this week, the Guardian reported that the Roman cities of Lepcis Magna and Sabratha both survived the war without any significant damage. This news came from Dr. Hafed Walda, a Libyan scholar working at King’s College, London. Dr. Walda has excavated and studied Lepcis Magna for more than 15 years.

On the other hand, the new government displayed a cache of Roman artifacts that it says were going to be sold on the international antiquities market to finance Gaddafi’s fight to stay in power. They were found on the day Tripoli fell to the rebels in the trunk of a car driven by Gaddafi loyalists as they tried to escape. No word on what happened to the pro-Gaddafi fighters. One can imagine.

This brings up the question of how many more artifacts were stolen from museums and archaeological sites, and if any made it abroad into the hands of unscrupulous collectors. Iraq and Afghanistan lost a huge amount of their heritage this way. Much of it disappeared after the main fighting, when armed bands looted what they could before a new regime was installed.

%Gallery-140657%Thousands of coins dating to the Greek, Roman, Byzantine, and Islamic periods have gone missing from a collection in Benghazi, the new Libyan government reports.

These are, of course, only initial reports in a country still subject to much chaos and uncertainty. Time will tell how much of Libya’s rich archaeological heritage has survived to attract the next generation of tourists.

I want to be one of the first of that new generation. Libya has always been high on my list of places to see and my wife and I were in the beginning stages of planning a trip there when all hell broke loose. Instead I spent two months out of harm’s way in Harar, Ethiopia.

For anyone interested in history and archaeology, Libya is a great place to go. The nation has five UNESCO World Heritage Sites. The two most popular are the Roman cities of Lepcis Magna and Sabratha. Both are on the coast and were founded by the Phoenicians. Libya was an important province in the Roman Empire and these two sites reflect that with their theaters, broad avenues, and large temples. Lepcis Magna was especially grand because it was the birthplace of the Emperor Septimius Severus (reigned 193-211).

Other UNESCO World Heritage Sites in Libya include the Greek colony of Cyrene, the prehistoric rock art of Tadrart Acacus, and the traditional architecture in the oasis town of Ghadamès.
